SUMP compatible logic analyzer for Arduino
|
||||
==========================================
|
||||
|
||||
NOTE: With v0.11 you can now sample at 4MHz & 2MHz rates in addition to the
|
||||
previous 1MHz and lower rates. This is done via unrolled loops which
|
||||
makes the source code huge and the binary takes much more of the flash.
|
||||
v0.11 is just slightly to big for an ATmega168's flash. You can comment
|
||||
out either captureInline2mhz() or captureInline4mhz() and it will fit.
|
||||
|
||||
NOTE: v0.09 switched the channels BACK to pins 8-13 for trigger reliability.
|
||||
Please report any issues. Uncomment USE_PORTD for pins 2-7.
